(Cover) - EN Showbiz - Bradley Cooper and Jennifer Lopez are enjoying a "casual" romance.

The pair were first romantically linked when they were spotted having dinner in New York City last month. Over the weekend, Bradley was photographed in Los Angeles driving a car while a woman resembling Jennifer attempted to cover her face.

Although the stars are attracted to each other, they reportedly don't want to rush into anything serious.

A source close to the pair has told TMZ that they are "casually dating" but aren't a couple quite yet.

They are also reporting that the woman trying to hide her face in Bradley's car was "definitely" Jennifer. It is believed they want to keep their blossoming romance out of the spotlight.

"While they aren't boyfriend/girlfriend yet, they are definitely dating," the website added.

Bradley, 36, has been linked to a host of women since splitting from actress Rene Zellweger in March of this year. He is believed to have flirted with beauties including Jennifer, Olivia Wilde and Scarlett Johansson.

Jennifer, 42, announced she was separating from her husband Marc Anthony in July. (C) Cover Media
